Emamectin benzoate (MK-0244) is a novel semi-synthetic derivative of the natural product abamectin in the avermectin family of 16-membered macrocylic lactones. This epi-methyl amino derivative has unprecedented potency against a broad spectrum of lepidopterous pests with LC90values ranging between 0.001–0.02 ug/ml in ingestion-based foliar spray assays. Emamectin benzoate is ca. 1,500-fold more...
